Abstract (en)

[origin: EP3333932A1] The present invention relates to a battery system (100) that comprises at least one plurality of aligned battery cells (80) arranged in a first direction (y). Each of the battery cells (80) comprises a vent hole (88). The battery system (100) further an extinguishing system (60) with a reservoir (61) for an extinguishing agent and at least one conduit means (62) for conducting the extinguishing agent, wherein the conduit means (62) is positioned such that it is hit by a vent-gas jet emitted by any of the vent holes (88) of the plurality of aligned battery cells (80) and wherein the at least one conduit means (62) is configured to be melted by the vent-gas jet. The invention further relates to a cooling circuit (70) for a battery system (100) comprising at least one plurality of aligned battery cells (80), each of the battery cells (80) comprising a vent hole (88). The cooling circuit (70) comprises a conduit means (72) configured for conducting an incombustible or flame-retardant coolant and an evaporator (71) that is in thermal contact with the a first plurality (91) of aligned battery cells (80) and that is configured for causing the coolant to absorb heat from the first plurality of aligned battery cells (80). The conduit means (72) is positioned such that it is hit by a vent-gas jet emitted by any of the vent holes (80) of the first plurality (91) of aligned battery cells (80) and is configured to be melted by the vent-gas jet.
